Shimano 105 CS-R7100-12 12-speed Cassette

Shimano 105 CS-R7100-12 Cassette - 12 sprockets for the best drivetrain efficiency

The CS-R7100 is the first 12-speed cassette from Shimano's 105 road bike series. With only about 15 grams more weight than the Ultegra model, it offers fast and smooth shifting, even when you pedal hard. It has the same width as an 11-speed cassette, so the sprockets are closer together. This accommodates the speed and smoothness of shifting. The smallest of the 12 steel sprockets has 11 teeth and the largest 34, which means a very wide range that lets you find the right gear uphill, downhill and on flat terrain. This way you can move forward efficiently everywhere and maintain your flow. Also worth noting: the freehub of the CS-R7100 cassette is not only compatible with Shimano 12-speed freehub bodies, but also with conventional road freehub bodies.

Technology:

HG Cassette
Shimano Hyperglide cassettes (HG cassettes) have strategically-positioned ramps and special tooth profiles so that the chain can be completely guided directly onto the next sprocket. This prevents the chain from just touching the tips of the teeth before it actually touches down. This optimises the chain guide and enables fast, highly efficient shifting.
